STRAND-WORKING MACHINE.

Application filed December 11, 1923. Serial No. 680,023.

To all whom it may concern:

Be it known that I, HENRY GooDwIN HOORNBEEK, a citizen of the UnitedStates, residing at Springfield, in the county of I-Iampden and State ofMassachusetts, have invented certain new and useful Improvements inStrand-WVorking Machines, of which the following is a full, clear,concise, and exact description.

This invention relates to improvements in strand working machines, butmore particularly to a holder for material supply cops designed topreserve an even tension on the strand as it is drawn from the cop.

An object of this invention is to produce a holder for supply cops forstrand working machines, designed so that the material may be fed fromthe cop under uniform tension.

Another object is to provide a holder for supply cops of such a typethat the cops may be readily placed therein and removed therefrom.

To this end a cop holder has been designed in which the supply cop restson its outer peripheral surface in a support which allows the cop torotate freely and at the same time is longer than the cop a sufficientamount to allow a free. lateral movement thereof.

In the accompanying drawings,

Fig. 1 is a side view of the mechanism as it appears mounted upon atinsel serving machine, and

Fig. 2 is a front view of the same, showing just sufficient of theassociated machine to illustrate the position of the cop holder.

Referring to the drawings in detail, a frame 10 of a tinsel servingmachine of some well known type supports a serving head 11 which servesa strand of tinsel 22 on a central strand 21 in a well known manner. Acapstan 30 is driven by the same means as the tinsel serving machine ofwhich it forms a part and by its rotation draws the strand 21 up throughthe tinsel serving mechanism, through a guide 31 and the tinseled strandis then wound on a takeup spool (not shown) in a well known manner.

A holder 'is provided for a supply cop,

consisting of two side plates 40, a supporting member 41, to which theside plates are fastened by rivets 42, and a cradle of polished rods 43connected to the side plates by "suitable means, for instance riveting70.

and the strand 21 therefrom is passed be-' tween the tensioning guidediscs 50 which may be regulated as to the tension they apply by turninga knob 52. The strand is then drawn through the serving head 11, throughthe guide 31, around the capstan 80 to the takeup spool (not shown). Themachine is now ready for operation. On starting the machine the capstan30 rotates and draws the strand 21 from the cop 20 and up through themachine where it receives the tinsel as it passes through the servinghead 11.

The arm 51 carrying the tensioning guide discs 50 is fixed, and owing tothe fact that the strand is wound upon the cop diagonally, the tensionrequired to draw the'strand from the cop increases greatly with theangle at which the strand leaves the cop. Furthermore, where the centerof the cop is held in front of the guide discs during the entireoperation the strand is more likely to snag when being drawn from theends of the cop than it is when being drawn from the center.

With the holder embodied in this invention the cop is free to move fromend to end as shown. the strand leaves the cop tendsto remain in frontof the guide discs during the entire operation, and thereby preserves auniform tension on the strand at all times.

Thus the point at which The force necessary to move the cop lateringmachines, comprising a cradle composed of rigidly fixed end pieces andinterconnecting spaced rods arranged in an arc to supcop is free toslide longitudinally of the port the cop horizontally at spaced pointson rods.
